摘要
A radio-frequency (RF) switch includes a field-effect transistor (FET) disposed between a first node and a second node, the FET having a source, a drain, a gate, and a body. The RF switch further includes a coupling circuit including a first path and a second path, the first path being connected between the gate and one of the source or the drain via a first resistor in series with a first capacitor, the second path being connected between the body and the one of the source or the drain via a second resistor in series with a second capacitor, the coupling circuit configured to allow discharge of interface charge from either or both of the gate and body.
